Lui Marco on dieting

This guy seems to have a very large fanbase on youtube. I haven't seen a single youtube comment that goes against his beliefs. I was wondering what you guys think of this video. Is there any truth to his statements?

'We need that post workout shake and it has to contain simple carbs for recovery....no body is trying to doubt the SCIENTIFIC reality.....the rice the spaghetti the bread the slow carbs it doesn't make sense' ......So basically FU AA is what he is saying. He knows science
